这一事件的深层原因是什么？

深入分析可以发现，Behind the scenes, Serde doesn't actually generate a Serialize trait implementation for DurationDef or Duration. Instead, it generates a serialize method for DurationDef that has a similar signature as the Serialize trait's method. However, the method is designed to accept the remote Duration type as the value to be serialized. When we then use Serde's with attribute, the generated code simply calls DurationDef::serialize.

专家怎么看待这一现象？

多位业内专家指出，Once we have defined our context-generic providers, we can now define new context types and set up the wiring of value serializer providers for that context. In this example, we define a new MyContext struct, and then we use the delegate_components! macro to wire up the components for MyContext.
